Airworthiness Directives; the New Piper Aircraft, Inc. (Formerly Piper Aircraft Corporation) Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 Airplanes

摘要

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain New Piper Aircraft, Inc. (Piper) Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 airplanes. The proposed action would require a complete landing light support replacement. This proposed AD action is prompted by reports of two accidents and two incidents resulting from the landing light retainer support seal breaking apart and entering the carburetor. The actions specified by the proposed AD are intended to prevent the landing light retainer support seal from being ingested by the updraft carburetor, which, if not detected and corrected, could possibly result in rough engine operation or engine stoppage.
